The chip on the camera fell out. How to solder it? [Copy link]

There was a little bit of cold soldering, so I took it off, but the solder got lost, and I don't know how to solder it back on.

You can't buy such a tin mesh

You can fix this BGA too~ I changed an air gun and blew for a long time. If the solder ball is still there, you can hold the air gun with tweezers and blow it. Now these are all ball-planting steel meshes. It is very difficult to brush them. It is also easy to have large and small balls. If the solder ball is not there, you can add some balls again, but it is not easy to add~ When hand soldering, the pad must be cleaned, otherwise there will be a risk of solder creeping and shorting.

First, the chip is balled, then solder paste is applied with a syringe, and finally the hot air gun is used to blow solder. However, it is easier said than done. Some mobile phone repairmen know how to do this skill. In the past, there were also people who helped solder BGA. When the number of pins was small, a hundred yuan was enough. I don't know if there is such a thing now.

The vibration was too big and it fell off.

The BGA solder balls are gone. This is really a job that tests your skills. You can try the universal steel mesh ball planting.

The solder balls are gone , so I'll just treat it as practice. Thank you all. I've already bought a universal steel mesh, but haven't tried it yet.

What kind of soldering quality is this? The BGA chip can even fall off the PCB by itself? What is the OP doing?
